What is the range of the function: {(2,3), (4,3), (6,3), (8, 5)?

Back

3, 5

Front

Is this a function? (Use the vertical line test)

Back

No, because a vertical line touches more than one point on the relation.

Front

Is this a function? (Use the vertical line test)

Back

Yes, because a vertical line touches only one point on the relation.

Front

What is the domain of the function: {(2,3), (4,3), (6,3), (8, 5)?

Back

2, 4, 6, 8

Front

Is this relation a function: {(3,2), (3,4), (5,6), (7, 8)?

Back

No, because the x-coordinate of 3 repeats itself.

What is the vertical line test?

Back

A method to determine if a relation is a function by checking if a vertical line intersects the graph at more than one point.
